Variety, elegans Verrill. 



Plate III; Figures i, 1a. 



This species was the type of the genus. According to 

 Mr. Lyman's original description and figures his type differs 

 considerably from our specimens. I have, therefore, thought 

 it desirable to give new figures of our examples, and to de- 

 scribe the differences, which do not, however, appear to be of 

 specific value. But as our specimens are only a trifle larger 

 than his type, which was 9 mm. across the disk, the differ- 

 ences are probably not due to age.
